The Boxster, being of warped mind and unsound body, wills you his non-allegiance standard for college sports. Pesky little Boise State playing the underdog to perennial heavyweight Oklahoma is a case in point, it's fun to pick an underdog and enjoy their success - even if you are the kind of guy who wants Sweet Polly Purebred to wind up as a lab assistant to Simon Bar Sinister, if only to get her off the street. But I digress.
Now, as a cat, you truly cannot support dogs, dawgs, or puppies. Being that cats are anti-social in their own right, there should be no interest in supporting cats, lions, or tiggers. Mustangs or show horses, they'll just step on your tail, and the same goes for steers and buffalo. Wolves, wolverines, coyotes, gators, eagles, hawks etc. are just looking for a kitty snack.
Off the top of my head, the only college that might remotely interest a cat is Ball State
http://www.ballstatesports.com/SportSelect.dbml?DB_OEM_ID=14200&SPID=7633&SPSID=67657, not only are they named after a popular cat toy, but their logo indicates they identify with a small tasty bird. But as dryheat noted, they probably won't be on TV much, you'd have to listen on internet radio.
Perhaps a second option is Wesleyan University
http://www.wesleyan.edu/athletics/football/, not only are they into red and tiny tasty birds, but they did produce BB and Mangini, and even have a small sop to Miss G-cat as the alma mother of Patsfans own drewish princess, patchick. Again, you'd need to listen on internet radio.
You could also sign on with Uncle Box's new program, support a dysfunctional college football program. For my first victim I've chosen The University of Regina
http://prometheus.cc.uregina.ca/cougars/, not only does the name Regina make fans of
Who's Line Is It Anyway snicker, but while they call themselves the Cougars, the football team is called the Rams? Plus it's football in Canada. I'm just disappointed that curling isn't a varsity sport.
As the only twin brother I have in England, I've made an effort to help you with this new project. However, at the risk of offending Miss G-cat, I strongly recommend you wrap yourself around some ale and husband your remaining sanity by throwing darts at the college football schedule and rooting for whomever got the sharp end.
